6, four molluscum bodies and an epithelial cell as seen with a dry 

 lens ; one molluscum body showed protoplasmic motion ; 7, four 

 molluscum bodies, one encapsuled, another segmented ; 8, molluscum 

 body encapsuled within an epithelial cell ; 9, similar to 8, but showing 

 a globule being extruded ; 10, encapsuled molluscum body, bacteria 

 outside but not inside the capsule ; 11, unencapsuled molluscum body 

 segmented and invaded by bacteria : this is the end of a culture

Tumours were ground up with 1 to 2 c.c. of saline solution 

 by means of a pestle and mortar, and filtered through the

 examination confirmed the clinical diagnosis. The article
